What is the maximum enlargement you heard of?
Before hitting this forum, I remember seeing an advertisement for a product called the JES Extender. This was over 18 months ago. It claimed that the world record belonged to some dude who went from 1.8 inches to 7.5 inches. A whole gain of 5.7 inches! I know it was supposed to be from this device as well as surgery I think.
Any gains boosted by members or such of this magnitude?
